'Patented July 4, 1916.

To all Iwhom 'it ymay concern Be it known that l, EnwrN A. REED, a citizen of the United States, residing in the city of St. Louis and State of Missouri,l1ave invented new and useful Improvements in Dough-lllolding Machines` of which the fol* commonly employed for coiling the sheet 'of dough upon itself to form a roll involve, in one form or another, an element, commonly denominated a curling plate, which is rigid throughout its length. These curling plates, while capable of yielding bodily to acconnnodate the increasing-width of the roll as the sheet of dough is coiled upon itself,

vcan onlyin practice act upon one portion or sheet of dough. at a time, as it is held too far away from the supporting element, usually a revolving drum, by the thickness of the coil of dough to enable it to act upon a fresh sheetof dough entering between it and the drum. It is therefore necessary that the coiled sheet of dough pass entirely from beneath the curling plate before the latter can act upon a second sheet of dough passed between it and the drum. The capacity of the *machine is thus 4necessarily limited. Again, the solid curling plates frequently exert too great an initial pressure upon the dough by reason of their unyielding character, which results in what lis technically known as punishing the dough.

It is the general object of `my invention to provide a curling element, which I' term a curling apron, to be used in place of the ordinary curling plate, which shall be yielding throughout so that it may exert a gentle pressure upon the dough, and will furthermore be enabled to act upon a coil, or several coils, of dough of the maximum diameter at one portion of its lengthand at the same time engage the end of a fresh Sheet of doughto rcoil the latter.

A. further advantage incident to the. use of my flexiblecurling apron is that owing to its clinging natureit insures the even and complete coiling of the sheet of dough without undue pressure.

Dough molding machines of the type to which "my invention relates usually involve theuse of a kneading strip or plate partially surrounding a rotatable drum with means for adjusting such kneading plate toward and from the drum to var v the pressure toV be exerted upon the coiled roll of dough which is caused to pass between such plate and drum. So far as I am aware, such fadjustinentlspf these plates as have heretofore been devised do not permit of separate adjustments of the ends of said plates. but they are adjusted as a whole toward or from the drum.

lt is` therefore. a further object of my invention to provide improved means for separately adjusting the end 'portions of the kneading plate toward or from the drum in order to graduate the pressure to be exerted upon the roll of dough if so desired.

The invention also involves certain novel vcombim'itions and operations of parts, and

these latter. with the advantages incident thereto, will be fully set forth in the following specification.

In the accompanying drawiugs-Figure l .is a view in side elevation of a dough molding, machine constructed according to my invention; Fig. 2 is a central longitudinal sectional view thereof; Fig. 3 is a view in front elevation of the machine; Fig. 4 is a section on-the line Jf-l of Fig. 3, and viewed in the direction of the arrows; Fig. 5 is a section on the line of Fig. El, and viewed in the direction ot' the arrows; Fig. is a section through the curling apron and drum taken on the line t of Fig. Fig. 7 is a detached perspective view of the curling apron; Fig. 8 is a perspective view of the pivotal support for the apron; Fig. 9 is a detached view of a portion of Fig. 2 showing the curling apron as it appears when aeting upon one or more portions of dough; Fig. l0 is a sectional detail viewl illustrating the connection of .an adjusting screw for adjusting the kneading plate; Fig. 1l is a detached perspective, view, on en enlarged Scale, showing a portion of the kneading plate with a locking bracket secured there on; Fig. 1 2 is a similar view showing a pivoted locking dog for cooperation with the locking bracket on the kneading plate; Fig. 13 is a longitudinal sectional view, also on an enlarged scale, through a portion ot' the drum showing a modified construction of curling apron supported in relation thereto; Fig. 14 is a plan view of a portion of said modified construction of curling apron; and Fie'. 15 is an edge view of one of the links thereof.

Referring nov-to these drawings, the numerals 1,' 2, indicate side frame members supporting the working parts of the machine, and which are mounted on a base 3. The rameinembers 1, 2. provide substantially' midway of their height, supports t on which are mounted in suitable bearings a shaft 5. Secured on the shaft 5 is a hub 6 from which radiates spokes 7 which support a drum 8, rl`he drum 8 is provided at opposite sides with annular flanges 9, the distance between which determines the length of the roll, or loaf, to be molded.

The numeral 10 indicates the kneading plate which, as shown, surrounds the lower half of the drum 8 at a distance therefrom. Secured on the under side and centrally of the kneading plate 10 is a lug 11 which is provided with a verticallydisj)osed slot 12. Mounted on the base 3, beyond either side of the drum 8, are two corresponding bracket-members 13 which support in their upper ends a rod or pin 1t which passes through the slot 12; and the latter, working over the bolt 41., serves to guide the movement of the lower portion of the kneading plate, restricting such lower or body portion to movement in substantially a vertical direction as the ends ot' the kneading plate are adjusted toward and from the kneading drum 8. The construction also permits pivotal movement of the lug 11 about the bolt 14, if such should be caused by the degree of adjustment of the kneading plate. Pivotally mounted at 15 on the frame members 1, 2, are pairs of arms 16 projecting from the front and rear of the machine, respectively, and connected by a cross bar 17. Extending between each pair of arms 1G and secured in the outer ends thereof, is a crossrod 18.

I provide disengageable means for dctachably latching the arms 1G to the kneading plate. For this purpose the kneading plate l0 has secured on its under si de near one end a bracket 19 provided at opposite ends with ontwaIdly-projecting` arms 19 which are connected by a web 19". This `web is cut away to form a T-shaped recess 19 which provides two projections 19d directed toward each other. The outer ends of ,the arms 19 are provided with semi-circular ,recesses 19 .it is desired to remove the kneading plate,

it is only necessary to turn the dog 19 upward by hand. The opposite end of the kneading plate to that just described is provided with a locking bracket similar to that just described, as indicated at 20 in Figs. 1, 2 and 3, the bracket 2 0, however;

being provided with an upward extension 2()u which is provided with a socket in its upper end t0 receive a standard 21 which supports a receiving table 22. T he arm 16 and cross-bar 17 are preferably, though not necessarily, formed as an integral structure. One bar 16 of each pair has swiveled there` in intermediate .its ends, as indicated at 23, (see Fig. 10) a stud 24 which is provided with a ,screw-tln'eaded aperture to receive the screw-threaded end of an adjusting screw 26 which is mounted at its upper end in abracket member 27 of the frame mem ber 1 in such manner as to be capable of rotation while being prevented from having vertical movement. I prefer to provide means mounted in a fixed position on the frame for independently adjustingr the end portions ot' the kneading plate 10. For this purpose each adjusting screw 2G is provided with a hand-wheel 28 with its hub mounted to rotate in a fixed position in the frame, (see Fig. 10.) By turning either adjusting screw 213 the arms 1li will be raised or lowered, and the corresponding end of the kncading plate l() brought nearer to or farther from the periphery ot' the drum, 8 according to the directionl in which the adjusting screw is turned. It will be apparent to those skilled in the art that this construction will permit ot' a wide range in, and variation of, the adjustment of kneading plate 10 without particularizng this teature more in detail. In such adjustments the pin and slot connection at the bottom of the kneading plate heretofore described will control the iiex oit the apron and prevent its 'bulging uncqually on opposite sides ot' its median line.

I will now describe my improved curling apron, andthe manner oit' mounting the same on the machine, having reference particularly to Figs. 2 and 9, and. Figs. (3 to 8, illustrating the preferred form thereof. The curling apron proper" is indicated generally by the numeral 29, and comprises a strip of canvas, or other fabric, or flexible material, 30, 'secured to one side of which and extending transversely thereof in par'- allel relation from end to end of the strip are a series of rounded strips 31,'which may be of wood or metal. The curling apron hdas'secured on its upper side, at what may be termed its forward end, two apertured brackets 32, and secured at intervals along Vthe sides Aof the' apron andA projecting upward therefrom, and outward from such sides, are a series of -Lshaped supporting arms 33. y

The numerals 34 (see particularly Figs. l, 2 and 6) indicate two corresponding curved supports which are secured at their upper ends to the frame of the machine, as indicated at and are curved concentrically with the ianges 9 of the drum but projectslightly above the saine and are located outside of said flanges, as indicated more part/'icalarl-y/iiig. 6.

The supports 34 are connected and braced at their. lower ends by a cross-rod 36. lVhen in position on the machine the curling apron 29 lies betweeii th'fianges 9 with the angle arms resting on the supports 3l, thus sup porting the curiing apron and holding it olit of contact with the periphery of the drum 8.

Referring to Fig. 8, the device there shown constitutes` a pivotal support and holder for the curling apron, and comprises two side bars 37 rigidly connected toward what may be termed their rear ends by a cross-bar 38. The rear end of each side bar 37 is provided with a semi-circular recess 3f and the JforwardA end of each side bar with an aperture 40, The curling apron support is pivotaily connected to the curling'apron by means of a bolt 4l passing through the bracket members on said apron, andthrough the apertures l() in the ends of the side bars 37, the ends of said `side bars being positioned between the brackets 30. Sccured on the rear side of-each of the frame members l, Q, are bracket arms 42 which have iixedly secured in their outer ends a rod 43 which extends between them. This rod is adapted to be engaged by the recesses 39 in the ends of the side bars 37,/ The curling apron support thus holds/the curling apron in a relatively fixed position on thev machine while having a pivotal movement on the rod 425 to permit the forward end of the apron to rise as the doughpasses under it.

Referring to Fig. 8 it will be seen that each of the side bars 37 is provided with an enlargement 4l at its forwardend, which is of a length suliicient to extend over, say, three of the\st1ips 251 of the curling apron, '.lhis construction causesthel weight of the forward end of the support to be exerted in operation to resist slightly the upward movement of the first three strips. thus pro? viding a desirable amount of pressure to insure the coding ot the end of the sheet of dough as it passes under the apron. An additional object subserved by this construction is to prevent the first or end strip 31 from falling into contact with the rear end of the sheet of the dough being coiled; z'. e., the forward end of the apron will remain elevated until the sheet of dough has completely passed beyond it, then it is permitted to drop again to the original position to receive and act upon a succeeding sheet of dough. The length of the sheet of dough passed to the curling apron must bear suitable relation to the extent of the enlargement 4l to get the best result. To this end the rolls hereinafter referred to for forming the dough into sheets are relatively adjustable. and the length of the sheet of dough can be regulated by the adjustment of said rolls.- To the rear of the heads 44 the side bars 37 are reduced in width, as indicated at 45, such reduced portion providing a space which permits of the apron being raised without raising the side bars 3T. construction, as illustratedin Fig. 9, my improved curling apron will accommodate between it and the drum a coil of dough 46 of the maximum thickness toward its rear end or, in fact, at any point beyond, or to the rear of the heads 44,. without in any manner affecting the action of the apron upon a sheet of dough 47 just entering under the forward end thereof.

In the, modified construction of curling apron shown in Figs. 13, 14 and l5. I employ a series of pairs of links 47a. each pair .of links being connected at their lower ends by an integral curved crossbar 47". lthe length of each of which is substantially equivalent to the space between the flanges 5) of the drum 8, and adjacent links at each end of the cross-bar 47" being pivotally connected in the lnanner of a sprocket chain, as indicated at 47C. The cross-bars 47 are provided on their upper side with a centrallongitudinal strengthening rib 47, which at its opposite ends provides threaded sockets 47 for receiving thc screwthreaded ends vof angle-arms 47f which extend over and rest upon the curved members 34 in tho same manner as described with reference to the preferred constructionof apron, `and. thus support the cross-bars 47h at the proper distance from the surface of the drum 8. The forward end of the curling apron is pivotally connected. as indicated at'47, to

the forward ends of the side bars v37 of the' apron holder in like manner as previously described. -In this construction, while the kne-ading surface presented by the crossbars 47 is not continuous, yet the operation is substantially the same as with the preferred form of construction previously described, the pivotal connection between the link's permitting eachcross-bar 'toyield as a coil `of dough passes beneath it, and the By this curvature of said cross-bars corresponding to the curvature of the strips 31 and yield- ,ing substantially the same function.

Mounted on the upper ends oi' the side frames l and 2, and connecting them' is a superstructure 48, slidably mounted on which is a support 48a. Mounted in suitable bearings on the said superstructure and support, respectively, are two shafts 49 and 50. Secured to and extending upward from opposite sides of the superstructure 48 and the slidable support 48a are corresponding pairs of standards 5l, 52 the standards 5l providing at Ytheir upper ends bearings for a shaft 53, and the standards 52 providing bearings in their upper ends for a shaft 54. Mounted on the shaft 49 to turn therewith 'is a roller 55, and mounted on the shaft 50 to turn therewith is 'a roller 56, which is provided at its ends with annular fianges 57. The rollers 55 and 56 are mounted in parallel relation, the roller 55 being of slightly greater diameter than the roller 56, and being arranged to rotate between the annular flanges 57 on the latter. Mounted on the shafts 53, 54, to turn therewith are corresponding rollers 58 and 59. These rollers, and the rollers 55 and'56, are adapted to be rotated toward each other while being maintained in adjustable separated relation, through mechanism to be later described. Mountedv on the rear side of the superstructure 48 are arms 60 which are supported in termediate their ends by a cross-bar 61 ex tending between the standards 5l, said arms being curved to project over the rollers 58 and 59, and having mounted on such pro,-

jecting portions a hopper 62 for receiving successive lumps of dough to be fed by the hopper between the rollers 58, 59, and 55, 56, which roll the dough into sheet form, as will be understood.

Each ofthe arms 60 has secured on its inner side above the rollers 58, 59, a point-ed plate 63, the pointed portion of which pron jects downward between said rollers, said plates thus forming guards or stops to prevent the dough from ipassing over the ends of the rollers. The support 48*1 isadjustable to move the rollers 59 and 56 toward or from the corresponding rollers 58 and 55 by means of a screw-threaded shaft 64 `which engages in a screw-threaded aperture in a side flange of the superstructure 48, as shown by Fig. 2, und is swivcled, as indicated at 65, in a d wnwardly-extending flange 66 provided on the front end ot' the support 481. The shaft 64 is providedwith a hand-wheel 67 for turning it.

I will now describe the gearing and other mechanism for imparting rotation to the drum 8 and the rollers 55, 56, and 58, 59,

referring particularly to Figs. 3, 4 and 5.

Fixedly secured on one end of each o the shafts 50, 54,.is a disk 68, 69, respectively,

messes each of which is provided adjacent to its periphery and at preferably equidistant points with a number of outwardiy-project-- ing pins 70, four of such pins being shown on each of the said disks. The shaft 49 ei;- tends across the machine and projects from one side thereof, and on this projecting portion is secured a pulley 71 which is adapmd to be driven by a belt- (not shown) Secured on, the shaft 49 inside of the Jframe member 2 is a gear wheel 72 which meshes with a large gear wheel 73 secured on the shaft 5 on which the drum 8 is also secured. Mounted in a bearing provided, at the righthand side of the machine, as shown in Fig. 3, on the superstructure 48 is a stub shaft 74 on which is xedly secured a gear 75 in mesh with the gear 72. The inner face ot the gear 75 is provided with a circularlyarranged series of lugs 76 corresponding in, number with the pins on the vdisk 69. The end of the shaft 7l normally lies directly opposite the end of the shaft 50 and when in such position each pin 70 on the disk 69 will engage a corresponding lug 76. The shaft 49 has also mounted thereon a sprocket wheel 77 over whichand a smaller sprocket wheel 78 secured on the shaft passes a sprocket chain 79.

The numeral 80 indicates a standard .of the gear 82 is provided with a circularlyarranged series of lugs 84 corresponding in number to the number of the pins 70 on the disk 68. Normally the end of the vstub shaft 81 lies directly opposite the end of the shaft 54, and when in such position each pin 7 0 on the disk 68 engages a corresponding lug 84 on the gear 82. It will be seen that the rotation of the shaft 49 by the pulley 71 will cause the roller 55 to be revolved, and will rotate the drum 8 through the connection between the gear 72 andthe gear wheel 73. The rotation of the shaft 49 will also rotate the sprocket-chain 79 which will cause the shaft 53, roller 58 and gear 83 to be rotated, the latter, in turn, rotating the gear 82. As the latter rotate the lugs 84 will engage the pins 7 0 and rotate the shaft 54, thereby causing the revolution of the roller 59. In like manner as the gear 72 is revolved by the shaft 49, the engagement of the lugs 76 with the pins 70 on the disk 69 will cause the shaft 50 to be rotated. thereby causing the revolution of the anged roller 56.

The lug and pin connection illustrated in Figs. 4 and 5, an above described, is for the purpose of pe 'ttug the rollers 56 and 59 to be adjusted relative to the rollers 55 and 58 without breaking the driving connection. This adjustment, as previously explained, is accomplished by turning the hand-wheel 67 to move the support 48 carrying the rollers 56 and 59. In such movement the pins 70 on the disks 68 and 69 will, or may, be moved out of engagement with the lugs 76 and S4 on the gears 7 5 and S2, but as the lugs 7 6 and 84 will intersect in their movement the imaginary circle bounded by the pins 70 of the disks v68 and 69 it follows that said lugs will at some point in their movement engage the corresponding pins of the said disks and rotate the latter, although not of course in a strictly continuous manner. As a matter of fact, the lugs 7 6 and 84 present a sufficiently wide bearing surface for the pins to permit'of considerable movement of the shafts and 54 toward or away from the shafts 49 and 53 without carrying the pins 70 out of contact with the said lugs. Under any circumstances, in actual use the movement of the pins beyond the lugs will not be Sufficient' to modify to any great extent the continuous rotation of the shafts 50 and 54. In. the

. movement of the roller 59 outward a space will be providedbetween said roller and the pointed plate 63 which would allow the escape of the dough. To obviate this I mount-on the bearing of the shaft 54 a plate 85 (see Fig. 1) which extends parallel to the plates 63 and in slidable engagement therewith so as to cover the opening formed by the movement of the roller referred to.

The parts being in motion by power derived from the driving pulley 71, a portion of dough placed in the hopper 62 will pass' between the rollers 5S and 59, and then between the rollers 55 and 56, the arrangej by preventing any sliding movement of the ment of gearing being such Athat the latterrollers will have a greater surface speed of rotation than the rollers 58 and 59. vThis construction results in the lower set of rollers imparting a slight pull to the dough, which is desirable as a part. of the kneading operation, and also as preventing the dough from slacking and doubling upon itself between the upper and lower rollers. As the sheet of dough passes from between the lower rollers lits end engages the surface of the drum 8 and is carried into engagement with and under the end of the curl# ing apron 29, as illustrated in Fig. 9, and in the continued movement thereof caused bythe rotation of the drum 8 the sheetof dough will be coiled upon itself, due to contact with the said curling apron, and as illustrated at 46 in safid Fig. 9. The ribs 31 greatly facilitate this ceiling operation dough over the under surface of the curling apron. As the coil of dough passes from under the curling apron it enters the space between the l`kneading plate 10 and the drum, and is carried around while being constantly rolled, and is then delivered on the receiving table 22 in the usual manner. As heretofore described, the kneading plate 10 may be adjusted through the medium of the adjusting screws 26 to'vary the extent of pressure of the kneading plate on the dough, or to graduate such pressure in a manner that will be well understood by those skilled in the art.

One of the advantages arising from the use of the pin 14 and the slot 12 is that I am enabled to use different sized drums and different sized kneading plates on the same frame of machine without entailing any change of dimensions or alterations of the pin and slot. If a smaller or larger drum is used, a smaller or larger kneading plate can be readily substituted for the one in use. Evidently, also, such a substitution of different si'zjed parts can be effected without placing the kneading plate and drum out of alinement with each other.
